All men have an emotion to kill; when they strongly dislike someone they involuntarily wish he was dead. I have never killed any one, but I have read some obituary notices with great satisfaction.
There are a lot of myths which make the human race cruel and barbarous and unkind. Good and Evil, Sin and Crime, Free Will and the like delusions made to excuse God for damning men and to excuse men for crucifying each other.
Those who enjoy the emotion of hating are much like the groups who sate their thirst for blood by hunting and hounding to death helpless animals as an outlet for their emotions.
I am not afraid of any god in the universe who would send me or any other man or woman to hell. If there were such a being, he would not be a god; he would be a devil.
